AB 982 amends the Surface Mining and Reclamation Act to create a structured process for surface mining operations that go idle. Operators must file an interim management plan within 90 days of becoming idle; that plan is treated as an amendment to the approved reclamation plan, is exempt from CEQA, and may remain in effect under a nested renewal schedule.
The bill also creates a discretionary “Idle Reserve Mine Status” for construction-aggregate operations that meet narrow state-determined criteria and allows the Division of Mine Reclamation (DMR) to review those applications for a fee.
Why it matters: the bill provides a legal pathway that lets some aggregate operators delay reclamation while preserving reserves for future infrastructure. It locks in continued financial assurance obligations, creates new administrative steps and timelines for local lead agencies and the state, and requires annual public reporting of surface-mining statuses — changes that practitioners in mines operations, local permitting, and public works planning will need to operationalize quickly.
At a Glance
What It Does
The bill requires operators to submit an interim management plan within 90 days of becoming idle; the plan is an amendment to the reclamation plan, stays in effect up to an initial five-year term with two potential five-year renewals, and can be extended further if the operation receives an ‘Idle Reserve Mine Status’ approved by the Division of Mine Reclamation and concurred in by the lead agency. Financial assurances remain in force while a site is idle.
Who It Affects
Construction-aggregate operators that go idle, county and city lead agencies that administer reclamation plans, the State Geologist and Division of Mine Reclamation (DMR), and infrastructure planners who rely on future aggregate supplies. It also affects regulators who prepare or review financial assurance cost estimates and appeals before the Surface Mining and Reclamation Board.
Why It Matters
AB 982 institutionalizes a trade-off between preserving future aggregate supply for infrastructure and delaying reclamation. That changes permitting workflows, creates a fee-for-review pathway at the state level, and adds public transparency requirements that can inform regional planning and environmental oversight.

What This Bill Actually Does
The bill builds a two-track process for mining operations that stop extracting but do not immediately reclaim. First, an operator that becomes idle must file an interim management plan with the local lead agency within 90 days; that plan is not a CEQA project and is treated as an amendment to the approved reclamation plan.
The interim plan is limited to necessary measures to keep the site compliant with existing permit conditions until the operator either resumes operations or begins reclamation.
Second, the bill defines a structured term for interim management plans: an initial maximum of five years, followed by up to two additional five-year renewals if the lead agency finds the operator complied with the plan. For surface mines that extract construction aggregate, AB 982 offers an optional path to request “Idle Reserve Mine Status” from the Division of Mine Reclamation.
That status is only available when the State Geologist certifies there are reserves sufficient for future infrastructure needs, the site is not on federal land, and the Division has received fewer than 12 such applications in the fiscal year. If DMR approves and the lead agency concurs, the lead agency may extend the interim plan term by up to an additional 10 years.The bill preserves the operator’s obligation to maintain financial assurances during idle periods or under Idle Reserve Mine Status.
It also lays out a cross‑jurisdictional review process: lead agencies forward interim plans to the state supervisor for comment, the supervisor has 30 days to comment if it chooses, and lead agencies must respond in writing and act on the plan within defined time windows. Operators can appeal denials and certain delays up to the state board, and the bill specifies hearing windows and a single opportunity to cure plan deficiencies.
Finally, DMR must compile and post annual data on active, idle, and Idle Reserve operations beginning in 2027, and applicants must reimburse DMR for actual review costs.
The Five Things You Need to Know
An operator must submit an interim management plan within 90 days of a surface mining operation becoming idle; the plan is exempt from CEQA and is treated as an amendment to the approved reclamation plan.
Interim management plans last up to five years and may be renewed twice (two additional five-year renewal periods), potentially keeping a site idle for up to 15 years under local approvals.
The bill creates a discretionary 'Idle Reserve Mine Status' for construction-aggregate operations if the State Geologist certifies reserve volumes for future infrastructure, the site is off federal land, and the Division of Mine Reclamation has received fewer than 12 applications that fiscal year.
Financial assurances required under Section 2773.1 must remain in effect while a site is idle or in Idle Reserve Mine Status; DMR may require applicants to pay actual costs for its review in addition to existing fees.
The bill tightens review and appeal timelines: supervisor comments have 30 days to be submitted; the lead agency must act within 60 days after supervisor comments (or 90 days if none); and the board must schedule appeal hearings within 45 days of receiving a complete administrative record.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Appeals for denial or delay; supervisor appeals on financial assurances
This subdivision allows an operator to appeal to the board when a lead agency denies a reclamation plan or financial assurance on grounds unrelated to the statute or fails to act within a reasonable time. It also gives the supervisor standing to appeal a lead agency’s approval of an inadequate financial assurance cost estimate to the board, and it requires operators to post the approved assurance amount while an appeal is pending (with different rules for new versus updated estimates). Practically, this creates a formal route to challenge local decisions and an explicit process for state-level scrutiny of financial assurances.
Board hearing rules, standards, and remedies
The board may decline appeals that do not raise substantial issues but must hear supervisor-filed appeals. If it takes an appeal, the board must hold a public hearing within 45 days of receiving a complete record (unless parties agree otherwise). The board reviews whether plans and financial estimates 'substantially' meet statutory and regulatory requirements and can either approve them or return them with a single opportunity for the operator to cure deficiencies within 30 days. For inadequate cost estimates, the board will include adequate cost items in its determination and instruct the operator to submit a revised estimate that supersedes the prior approval.
Interim management plans: submission, scope, and term
Operators must submit an interim management plan to the lead agency within 90 days of idle status; the plan may only include measures necessary to keep the site compliant and is not a CEQA project. If approved, the plan amends the existing reclamation plan. The initial term is up to five years; the lead agency may renew it for an additional five-year period and then renew that renewal once more, allowing local approvals to keep the plan in place through staged renewals.
Idle Reserve Mine Status: criteria, extension, and rulemaking
For construction-aggregate operations, the bill authorizes the operator to request DMR review for 'Idle Reserve Mine Status.' Approval requires the State Geologist to confirm reserves for future infrastructure, that the site is not on federal land, and a DMR annual cap on applications (fewer than 12 received that fiscal year). If DMR approves and the lead agency concurs, the lead agency may extend the interim plan’s maximum renewal period by up to 10 years beyond the base renewal schedule. The board must adopt implementing regulations and DMR is charged with compiling annual program statistics.
Financial assurances, review steps, deadlines, abandonment trigger, and enforcement hold
Financial assurances remain in effect during idle status or Idle Reserve Mine Status, and failure to maintain them leads to reclamation obligations. The statute prescribes review steps: lead agencies must forward complete plans to the supervisor for comment, certify completeness, and respond in writing; the supervisor has 30 days to comment; lead agencies must approve or deny within 60 days after supervisor comments (90 days if none). A site idle for over one year without an approved interim plan is deemed abandoned and must begin reclamation, and enforcement actions for operating without required plans or assurances are held in abeyance while review or appeals are pending.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Construction-aggregate operators that can document reserves: they get a defined administrative path (Idle Reserve Mine Status) to postpone reclamation and preserve reserves for future infrastructure needs, potentially avoiding immediate reclamation costs.
- Infrastructure planners and public works agencies: annual DMR reporting on reserve locations and mine status improves visibility into future local and regional aggregate supplies for projects.
- Operators with compliant interim plans: the CEQA exemption and a clear renewal schedule reduce procedural uncertainty and the immediate risk of forced reclamation while they maintain site conditions.
- Division of Mine Reclamation and state resource planners: DMR gains an explicit role and fee recovery authority to evaluate reserve qualifications and compile statewide data useful for planning and oversight.
Who Bears the Cost
- Operators seeking Idle Reserve Mine Status: they must pay DMR’s actual review costs (plus existing fees) and maintain financial assurances while idle, shifting near-term cash flow burdens to operators who wish to defer reclamation.
- Local lead agencies: they must adhere to tighter review timelines, produce written responses to supervisor comments, and manage potential extended renewal periods—adding administrative workload without explicit state funding.
- The Division of Mine Reclamation: DMR will see increased application and reporting burdens and must develop implementing regulations, likely requiring staffing or contractor resources even though it can recover applicant costs.
- Nearby communities and environmental advocates: potential extended idle periods can prolong disturbances, delaying reclamation benefits (e.g., habitat restoration) and complicating local land-use objectives.
Key Issues
The Core Tension
The bill forces a trade-off between conserving tomorrow’s construction-aggregate supply for infrastructure projects and enforcing prompt reclamation to protect environmental and community interests: it preserves financial assurances and creates controls, but it also permits extended idle periods that delay on-the-ground restoration and transfer administrative burdens to local and state regulators.
AB 982 crafts a carefully textured compromise but leaves several practical and legal questions. First, the Idle Reserve Mine Status is tightly circumscribed (State Geologist finding, off federal land, and a DMR application cap), which helps limit the program’s scope but also creates a queueing problem: a hard cap of fewer than 12 DMR-reviewed applications per fiscal year can produce an administratively driven backlog and a de facto lottery for operators.
Second, the bill preserves financial assurances during idle periods, which protects reclamation funding but raises questions about how cost estimates are updated over long idle horizons and how inflation, changed reclamation technologies, or increased remediation needs will be handled mid-term.
Implementation will also create coordination burdens. The lead agency–supervisor–board review ladder is procedural and time‑sensitive: supervisor comments, mandatory written responses, tight approval windows, and single opportunities to cure deficiencies create a choreography that local governments must operationalize carefully.
Finally, the statutory text contains drafting irregularities around the duration and inoperative dates for the reporting requirement (a stray date string appears in the text), which could invite legal challenges or require early clarifying regulations from the board or DMR.
